This invention felates to a punch especially adapted fo1' fnaking openingS in canS and like oontainers to be efnployed fof venting the can and the pouring of the contents thefefroIn.

The prin1ary object of the invention is the provision of a tool of the above stated oharacter which Win be extremely eaSy to handle and may be quickly applied ovef the end of a can and inoludes a pair of spaoed penetrating elements which nay be easily fofced thTough an end vvan of the can by pressure opplied on the hand1e of the device theTeby TuptuIfn3 the can at different paoes, providing in the oan the vent ono pouTing openings.

Another objeot of this invenfion is the pTo vision of n1eans fo' outonlatically vvithdravving the punotufing eleInents fron1 the can as soon as the preSSure iS Teleased on the ha1d1e of the device, pefInitting the device to be oonveniently feInoved fronf the oarn so thot the oan vvi11 be coIne vented and the contents poured therefroIn as desired.

vvith these and othef objeots in view as Wi11 beoonle Inofe apparent aS the deSofiption pfo oeeds, the inventfon oonsists in ceftain novel featufes of conStfuotiof1, oofnbinatiof1 and of rangenlent of parts as Wi11 be hereinaftef Inore funy desofibed and claimed.

Eor a, ooIT1plet understanding of ny inven tion, feference iS to be had to the fonowing de sonption and aooompanying dfawing, in Whioh 'igure 1 fs a vertioa1 Seotional vieW inust ating a punch oonstTucteo in accordance vvith Iny invention and Shovving the device a,pplied to one end of a, can.

Eigue 2 is 3 botton1 plan view inuStfating the dovioe.

Eigufe 3 iS oJ Seotional vievv taken on tf1e 1ine Referfing in detai1 to the dTawing, the nu n1eral 5 indicateS af1 annular body, one end of Which is closed by an end Wan s and the o po Site end of the annulaf body is beveled, as shown alt to naTe sarid end of the body so that it Inay be feadily inSefted ovef the end ofa can 8, aS Shown in i ure 1. The end Wa11 6 of the body iS provided vvith spaced openings to feoeive Scfew thTeaded Shanks 9 of punctuIing elements lo. Nuts are threaded on the shanks after paSS ing thTough the openingS of the Wan s providing aJ constfuotion Whjoh Wi11 pefn1ft the penetrating eleInents to be eaSily Temoved from the body should it be desired to sharpen the penetrating elefne11ts of feplace then1 by othefs.

t is pfefefable that the openings fof the pene tTating elefnentS be 1ooated oose to the anonlaf Wan of the body affanging the penetfat1g e1e Inents a suffioient distance apart so that When.

they Tupture the end Wa11 of the oa1 they Wi11 provide openingS thefeiI1 1ooated adjacent the vertioal wans of the can. one of the o penings Inay be enlployed for pouring the contents of the can vFhile th otheI' opening adn1its atfnosphefic preSSure so that the contentS vvi11 fioW fTeey.

A blook of Inatefial l2 is detachably Secured to the wan 6 of the body and is shoped to provide o hand grip. sorewS of like fasteners l3 are eInployed foI detachably securing the blook of nlateria1 to the body.

The blook of Inoterio1 haS fofIned theTe1 3 eceSs of different diameters and is adapted to aJign with an opening l5 formed i11 the wa11 6 of the body. The smanest diameter of the fe cess l l fornls a Sea t for one end of a coil Spring ls, the other end of the ooi1 SpfiI1g beof1g aga1St a cloSed end of a sleeve !8 slidable through the opening l5 and in the larger por tion of the feoess l4. The open end of the sleeve is anged, as shown at ls, acting os stopS fof pfeventing the sleeve ff'om being fofced entifely out of the recess l by the action of the Spring vvhen the devico is en1oved ffom a oan. The TeoesS having the diffefent dian1etefs os befofe specified provides an interna1 Shoulder 2 acthg as a stop to be 8butted by the fiange ls for liIniting the inWard moven1ent of the sleeve. The sleeve fnoy Inove invalfdly of the reoess l Sui cient to pefInit the penetfating elen1ents to pass through the end Wan of the can untifthe end Wa11 6 of the body conles in oontaot With the oof1. AS Soon aS pfeSSure is feleased ffon1 the hand'grip the Spfing actS to ithdraW the penetrating elefnentS ffon1 the can by fnovingthe end wa1 6 aWay f1'on1 -the end wa11 of the con.

-The device in this poSition as Shown in E,igue 1 fS Teady to befeInoved froIn the can or to feceive preSSure foI' driving the penetrating eleInents through the end wa11 of the can.

vvhile have shown and desoffbed the pTe feffed efnbodilnent of ny invention, it.Wi11 }e underStood that fninor ohangeS in oonStrffotion,
